There is a couple of switches in the 4x4 system that may be at fault. You would need to find out which one at the dealership. You are not supposed to be riding down the road with the ebrake on which is why the headlights go out.

brake and abs light check brake fluid level. The round float in the master cylinder directly controls the 2 dash lights.
The light is NOT directly controlled by the master cylinder float. The light is controlled by the ABS Module, which location depends on your vehicle. There are a number of different reasons the lights come on. If it comes on but shuts back off within seconds, don't worry about it, that occasionally happens when it gets a bad signal ("nonlatching error"). In rear-wheel-drive (RWD) vehicles, it is common for the differential speed sensor in the rear differential to go bad. You can pick up a Haynes manual to find if you can do at-home diagnostics (Temporarily grounding out the diagnostic lead will cause the ABS light to flash out a pattern indicating the error)

Check the Brake Pressure switch ( also known as SPEED CONTROL DEACTIVATION SWITCH ) which is located below the Brake fluid master cylinder for leakage. The leakage can cause both lights to stay on and also cruise control control not working

This is caused by by a bad ignition switch. According to the dealer the ignition switch contains an antenna that many of the sensors use to communicate with the vehicle, as well as the key fob. When the switch starts going bad the vehicle computer losses communication with these sensors and starts producing codes which include the 4wd and the electronic brakes. My fiance has had the same issues with her Grand Cherokee as well as the key fob not working, the remote start not working, the service engine light comes on, the door chime will sound when the key is NOT in the ignition and the lights are NOT on, as well as numerous codes usually relating to loss of communication with one system or another. All of which are fixed once the ignition switch is replaced. Unfortunately, this usually only fixes the problem for a short time (weeks or maybe a few months) before the piece of junk ignition switch fails again and it all starts over.
